dear GR community,

I have an OOT module for e.g. “QPSK Mod”, implemented as python source  
code. the python class contains a docstring, which I expect to see in  
the GRC tooltip. instead I see “undocumented” (cf. attach)

n.b. I can see the docstring w. python help() to the underlying class of  
thr GR block

is tooltip for OOT modules supported?

thx for any hints, stefs
